In the past week or so, I've noticed an audile "ding-ding" from my C4 when stopped at a red traffic signal and it turns green.

I tried looking this up in the Sunnypilot documentation and found the Green Traffic Light Alert, but it states that it is not available for the C4.

Am I imagining the "ding-ding" sound or has this been rolled out to the C4 before the documentation has been updated?

From this web page: https://community.sunnypilot.ai/t/visuals-settings/3690
I have the same ding when I’m first in line at a light. I remember toggling this setting when getting everything up and going.

Definitely works on my c4?

Noticed a "ding-ding" from my C4 this weekend when I was NOT the lead car at a red traffic signal.

I was stopped in a queue of vehicles at a red signal, about 5 or 6 back from the lead car. The signal turned green and the vehicle in front of me started moving and I heard the "ding-ding".

Sunnypilot has an option that explains this, but is apparenly NOT AVAILABLE with a C4:

Lead Departure Alert (Beta)
Plays a chime and shows an on-screen alert when you are stopped and the vehicle ahead begins moving. Useful for noticing when traffic starts flowing again.​
Toggle & Device Availability
Supported on: comma 3X/3 only. This feature is currently not available on comma four and cannot be forced via sunnylink.​

This setting also exists in BluePilot and does work with the c4.

The new lateral logic coming in 7.0 might be perfect for you then. The TI is for people who get annoyed even having to steer around a traffic circle, or those who have TRON encrypted vehicles.
On a related note, how often is Bluepilot updated with Sunnypilot? BP 6.0 came out in March, Sunnypilot 26.1 came out on May 6th and 26.2 came out yesterday. I'm not super familiar with how the branching works, so please excuse my ignorance.

Bluepilot was built around stability and reliability, the initial philosophy was to only sync when we released new features.

Since no one has volunteered to help run the fork now that I am stepping back, it only syncs when I'm bored or have a major new feature to add.

Fair enough and, as someone heavily involved in other volunteer endeavours, I totally sympathize ... it's always 1% of the peeps doing 99% of the work (and apparently even more extreme ratios in this scenario).

I'm happy to help out with the fork, I do think the themed UI is going to cause a huge maintenance headache though. I have a pending MR for fixing the C4 with your latest sync. Forking the UI is fine if you have people dedicated to keeping up with upstream features, but if it's a skeleton crew keeping conflicts to a minimum is key.

Once I get the Torque Interceptor work finished, I will come up with a path forward to keep bluepilot in sync. And yes it will probably mean losing the fancy UI.

Which parts of the UI are the “fancy” bits?
The steering wheel/brake/accel/regen indicator I’d imagine along with the radar for the speed of the car in front of you etc.
